There is a lot of discussion about where D is heading and how it is going to get there. And what you should know is all this discussion occurs on the newsgroup. Don't expect the content on the Discussion and Ideas page to be the most up-to-date. The D Conference page contains information related to past and possible future conferences related to D.

If you are interested in keeping a general idea about what is happening you will find the Planet D's RSS feed to be very nice as it follows many D related blogs. Another area that has been getting some movement has been on reddit D_Language

[Done 30 April -- Tango code is off-limits for Phobos] The Tango license issue needs to be sorted to the extent that Andrei and Walter feel they can safely look at the Tango code; OR we can decide that's not going to happen, and change the strategy for the Tango/Phobos? relationship.
